b(3c-7)-a(3c-7)=

Solution for b(3c-7)-a(3c-7)= equation:

Simplifying
b(3c + -7) + -1a(3c + -7) = 0

Reorder the terms:
b(-7 + 3c) + -1a(3c + -7) = 0
(-7 * b + 3c * b) + -1a(3c + -7) = 0
(-7b + 3bc) + -1a(3c + -7) = 0

Reorder the terms:
-7b + 3bc + -1a(-7 + 3c) = 0
-7b + 3bc + (-7 * -1a + 3c * -1a) = 0
-7b + 3bc + (7a + -3ac) = 0

Reorder the terms:
7a + -3ac + -7b + 3bc = 0

Solving
7a + -3ac + -7b + 3bc = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '7b' to each side of the equation.
7a + -3ac + -7b + 7b + 3bc = 0 + 7b

Combine like terms: -7b + 7b = 0
7a + -3ac + 0 + 3bc = 0 + 7b
7a + -3ac + 3bc = 0 + 7b
Remove the zero:
7a + -3ac + 3bc = 7b

Add '-3bc' to each side of the equation.
7a + -3ac + 3bc + -3bc = 7b + -3bc

Combine like terms: 3bc + -3bc = 0
7a + -3ac + 0 = 7b + -3bc
7a + -3ac = 7b + -3bc

Reorder the terms:
7a + -3ac + -7b + 3bc = 7b + -7b + -3bc + 3bc

Combine like terms: 7b + -7b = 0
7a + -3ac + -7b + 3bc = 0 + -3bc + 3bc
7a + -3ac + -7b + 3bc = -3bc + 3bc

Combine like terms: -3bc + 3bc = 0
7a + -3ac + -7b + 3bc = 0
